Title: Control device of ball-shooting game machine
Inventor: MAKINO YUTAKA
IPC: A63F7/02
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To provide a control device of a ball-shooting game machine wherein a sub-substrate can be normally controlled without using control data, in the form of data, in the control of the sub-substrate. SOLUTION: Prize ball number data, as parallel data of 4-bit, are transmitted from a principal substrate to a delivery substrate for 2 ms. Zero data are transmitted for succeeding 2 ms so that the prize ball number data are not transmitted. On the other hand, in a delivery substrate for receiving prize ball number data, numerical value '1' is added to the value of a read counter 83a every time prize ball number data other than '0' are received. When numerical values of the counter 83a are 4, 5, 6, read prize ball number data are written on first- third memories respectively. If two or more values out of the values written on the first-third memories are identical to one another, the values are fixed as prize ball number data.  Thus, prize ball number data in the form of data are not used in the control of the delivery substrate, and hence the delivery substrate can be normally controlled.
